To all whom t may concern.'

Be it known that I, ZivA POPIN, residing at New York, in the county andState of New York, have invented certain new and useful Improvements ina Heater for Waving Hair, of which the following is a specifi-y cation.y

This invention relates to a new and improved heater adapted to be usedin the art of permanent hair waving. f

One of the objects of the invention is to y be utilized in impartingwhat is known as a permanent set or curl, in what is known as a Marcelwave, that is to say, a wave in which the curl is imparted to a lock ortuft ofhair in a direction at right angles to its length, incontradistinction to a spirally formed curl or wave, such as is impartedin the now utilized processes of permanent hair waving.

A further object ofthe invention is to provide a heater which conformsto the shape of the head, whereby the inner' end of the wave to beimparted to the lock of hair will terminate at equal distances from thescalpf v A further object of the invention is to provide a heater` oftheabove character, which may be more easily positioned upon the hair woundupon a curler than has been possible to do with heaters as hithertoconstructed.

Other objects and aims of the invention, more or less specific thanthose referred to above, will be in part obvious and in part pointed outin the course of the following description of the elements,combinations, arrangements of parts and applications of principles,constituting the invention; and the scope of protection contemplatedwill be indicated in the appended claims.

In the accompanying drawing, wherein `I have illustrated a preferredform of embodiment of my invention:

Figure 1 is a plan view of theinterior of the heater in open position,electrical wiring being shown in dotted lines.

Figure 2 is an elevational upper side of the heater.

view of the Figure 3 is a sectional View taken substantially on the line3-3 of Figure 2, looking in the direction of the arrow; and

Figure 4 is a sectional view showing the manner in which the heater isemployed lin carrying out my improved process. A

Referring now tothe drawing, wherein similar reference characters referto similar parts throughout the several views thereof, the referencenumeral 1 denotes one part of the heater, and 2 the other part thereof,each lof said parts being of semi-cylindrical form, as shown, and hingedtogether, as at 8. Each part comprises an shell" 4, which is preferablyformed of a light material, such for instance as aluminum, and locatedin each core 5, each core having positioned thereon a coil of resistancewire, as indicated at 6. Pairs of leading-in wires 7 and -8 areconnected with the resistance wire on each core, so that when thecircuit is closed through the leading-in wires, the resistance wireswill heat the cores, whereby the surrounding parts will be vheatedthereby. Strips of insulating material 9 and 10 are outer hollow shellis a metallic shown interposed between the lateral sidesof the core andthe ends of the chambers within the shell '4, thereby preventing the'core from being displaced from its normal position within the shell.

The shell 2 at its free edge is preferably provided with a slot 11,which is adapted to receive a ton e 12 formed upon the free edge of theshell 1, as indicated in Figure 3 of the drawings. The parts are lockedin the position shown, as by means of a resilient wire clip 13, which ispivoted at 14 to the shell 4, and which is adapted to be positionedabout the hinged parts, as indicated in Figures 2 and 3. One of thesewire clips is provided at each end of the device, as indicated in Figure2.

It will be seein, therefore, that these clips serve to resiliently holdthe hinged parts in close relation about the hair to be treated. It willalso be noted that the parts 1 and 2 are arc-shaped in form, each havingthe concaved part 15 and the convexed part 16, so

' the free ends extended between the actual use the scription or ligureit will be on and that when the hinged parts are in close position theyhave the form of a'bent tube; the concaved part being intended toconform to the shape of the hair of which the wave or curl is to beimparted.

The use of my improved device is illus trated in Figure 4 ofthedrawings, in which cated at 17 is wound upon a curler 18, such asillustrated in my co-pending application Serial Number 297,765. v

Upon the curled hair is positioned a Y' moistened impregnated carrier19, such as illustrated. in my co-pending application, Serial Number297,767, said impregnated carrier being wrapped about the hair', andfree ends of the respective parts of the heater with the strand of hairbetween the ends of the carrier, as clearly shown in the drawings.

ver the curled hair, and the impregnated carrier, -is ositioned al splittube 20, which is prefera'bll7 composed of a pasteboard tube.

'With the. parts in the position shown, the wire clips 13 are swung intothe position shown in Figures 2 and 3 of the drawing, therebyresiliently locking the parts lto,- gether. The tongue and grooveconstruction of the free ends of the cylindrical shell parts serve as abaiile to prevent the heat from esca ing toward' the scalp, the latterbeing furt er protected against theheat by lmeans of the protectivedevice or shield lindicated at 21, which is of the construction shown inv my co-pending application Serial Number 297,766. f I

-It will ybe understood, of course, that in interior parts of the'devicewill be more closely associated with the hair, impregnated carrier andthe tube in the interior wall of the heater will be in close engagement;the slight separation of these parts shown in Figure 4 being in theinterests of clearness of illustratio It will accordingly be seen thatIhave provided a device well adapted to attain, among others, all theaims and objects above pointed out, in an extremely simple manner. Thedivided construction of the heater enables it to be readily positionedupremoved from the hair to be treated. It will also be noted that thecable 22, which is composed of the leading-in wires 7 and S, isdlsposedl mldway of the length of the heater, whereby when the same issuspended it will be nlcely balanced, thereby relieving any strainupon'the hair.

s many changes could 4be made in this construction without departingfrom the scope of the following claims, it is intended that alllmattercontained in the above deshown in the accompanying ters Patent is:

noted that the hair indib drawing shall be interpreted as illustrativeonly and not in a'limiting sense.

- aving thus described my invention what I Vclaim as new and desire tovsecure by Letl1. A heater comprising a pair of semicylindrical partshinged together, each part eing provided with a heating element, the

free meeting edges of said parts being so con-l stru-cted asto permit alayer of hair to pass therebetween.

2. In a device of the class described, in combination, a pair of semicylindrical parts hinged together and adapted when in closed position toembrace a lock of ha1r, each of said parts being provided with a heatingelement, the free meeting edges of said parts being so constructed as topermit a layer of hair to pass therebetween.

3. IIn a device of the class described, in combination, a pair of semicylindrical parts hinged together and adaptedwhen in closed sition toembrace a lock of hair, each o said parts being provided with a heatingelement, and means for resiliently holding said parts in closedposition, so that a space may be provided between the free meeting edgesto permit a lock of hair to extend therebetween.-

.4. In a device .of the class described, in combination, a pair ofhollow semi-cylindrical, hinged shells, each of which is provided with aheating element, means for electrically heating each .of said elements,and means for resiliently holding adjacent edges of said hinged shellsin closed position, the construction being such that a lock of hair mayextend between the adjacent free edges of said shells.

5. In a device of the class described, a pair of hollow shells, eachshell being semi-circular in form, and each shell being curvedlongitudinally of its length, means for hinging said shells together, aheating element in each shell, and means for supplying a cur- -rent toeach of said heating elements.

6. In a device of the class'descri-bed, va pair of hollow shells, eachshell being semi-circular in form, and each shell Ibeing curvedlongitudinally of its length, means for hinging said shells together, aheating element in yeach shell, means for supplying a current to each ofsaid heating elements, and means for resiliently holding said shellstogether.

7. In a device of the class described, a pair `of hollow shells, eachshell being semi-circuof said shells at its free end being provided witha longitudinally extending groove, and the other at its free end beingprovided with a longitudinally extending tongue adapted to Afit intosaid groove.
